usage: $(basename "$0") [OPTIONS] INPUT.MOV [OUTPUT.mp4]
Convert Fuji .mov quicktime video to .mp4 container, which makes native
playback possible on Android.
Under the hood, this will keep the video codec as-is (expected to be H264),
while encoding the audio as AAC (expected to be PCM originally).
It will also remove the timecode track, which can cause compatibility issues.
Options:
-h,--help Display this message
--crf NUM Set video quality rate factor (see -crf 22)
-s,--size SIZE Resize video to SIZE (e.g. 1920x1080)
--preset PRESET Set video encoding preset (slow/medium/fast/veryfast)
--vcodec CODEC Set video codec (e.g. libx264/libx265)
Examples:
Convert a whole directory, one at a time (ffmpeg messes up tty if parallel):
parallel -j 1 $(basename "$0") -- *.MOV
Re-encode a video at more reasonable bitrate to reduce size:
$(basename "$0") --preset veryfast DSCF1234.MOV
